Air intakes in front of the car are normally closed, but open up when cooling is needed for the battery and converter. The e-tron uses LED lights all-around, with very innovative adaptive front lights. The lighting pattern dynamically changes depending on weather conditions and oncoming traffic. There are no separate fog lights, as the headlights change the projection shape automatically in foggy conditions. The headlights also use the navigation system to know when a turn is coming up, focusing into the curve before the driver steers.
